Four distinct positions and any closed ordering
Twelve independent fair bits form four consecutive three-bit blocks. The entire twelve-bit outcome is sampled once and revealed automatically, one bit per step. Each block has three bits, not twelve. Players do not choose bits or arrange the blocks manually.
Terminal raw reward is one if some permutation of all four block positions forms a closed directed ring: every block’s final two bits match its successor’s first two bits, including the closing link. Otherwise reward is zero. Equal-valued blocks remain distinct positions and each position must be used once. This is an existence test, not a count of matching links or valid orders.
Manual refill below ten coins
A new local wallet starts at 1,000 free coins. The balance and fractional payout carry are stored in this browser’s localStorage. Whole coins are credited from each payout while its fractional remainder carries forward. They have no cash value.
Refill is manual and available only while idle with a balance below 10. It sets the balance to 1,000 rather than adding 1,000, and preserves fractional carry. It is neither a timed refill nor a reset available during a round. No promo code or deposit is involved.
Local storage and network requests
LocalStorage holds the demo balance and fractional carry. The page also makes network requests for Google Fonts and Statinside analytics, and its server can receive request information such as IP address and browser details. A local wallet does not mean all activity stays on this device.
